HTTPoison (HTTPoison v2.1.0) View Source
The HTTP client for Elixir.
The HTTPoison
module can be used to issue HTTP requests and parse HTTP responses to arbitrary URLs.
iex> HTTPoison.get!("https://api.github.com")
%HTTPoison.Response{status_code: 200,
headers: [{"content-type", "application/json"}],
body: "{...}"}
It's very common to use HTTPoison in order to wrap APIs, which is when the
HTTPoison.Base
module shines. Visit the documentation for HTTPoison.Base
for more information.
Under the hood, the HTTPoison
module just uses HTTPoison.Base
(as
described in the documentation for HTTPoison.Base
) without overriding any
default function.
See request/5
for more details on how to issue HTTP requests

Specs
put!(binary(), any(), headers(), Keyword.t()) :: HTTPoison.Response.t() | HTTPoison.AsyncResponse.t() | HTTPoison.MaybeRedirect.t()
Issues a PUT request to the given url, raising an exception in case of failure.

Specs
request(HTTPoison.Request.t()) :: {:ok, HTTPoison.Response.t() | HTTPoison.AsyncResponse.t() | HTTPoison.MaybeRedirect.t()} | {:error, HTTPoison.Error.t()}
Issues an HTTP request using an HTTPoison.Request
struct.
This function returns {:ok, response}
, {:ok, async_response}
, or {:ok, maybe_redirect}
if the request is successful, {:error, reason}
otherwise.
Redirect handling
If the option :follow_redirect
is given, HTTP redirects are automatically follow if
the method is set to :get
or :head
and the response's status_code
is 301
, 302
or
307
.
If the method is set to :post
, then the only status_code
that get's automatically
followed is 303
.
If any other method or status_code
is returned, then this function returns a
returns a {:ok, %HTTPoison.MaybeRedirect{}}
containing the redirect_url
for you to
re-request with the method set to :get
.
Examples
request = %HTTPoison.Request{
method: :post,
url: "https://my.website.com",
body: "{\"foo\": 3}",
headers: [{"Accept", "application/json"}]
}
request(request)
Specs
request(method(), binary(), any(), headers(), Keyword.t()) :: {:ok, HTTPoison.Response.t() | HTTPoison.AsyncResponse.t() | HTTPoison.MaybeRedirect.t()} | {:error, HTTPoison.Error.t()}
Issues an HTTP request with the given method to the given url.
This function is usually used indirectly by get/3
, post/4
, put/4
, etc
Args:
method
- HTTP method as an atom (:get
,:head
,:post
,:put
,:delete
, etc.)url
- target url as a binary string or char listbody
- request body. See more belowheaders
- HTTP headers as an orddict (e.g.,[{"Accept", "application/json"}]
)options
- Keyword list of options
Body: see type HTTPoison.Request
Options: see type HTTPoison.Request
This function returns {:ok, response}
, {:ok, async_response}
, or {:ok, maybe_redirect}
if the request is successful, {:error, reason}
otherwise.

request(:post, "https://my.website.com", "{\"foo\": 3}", [{"Accept", "application/json"}])
Specs
request!(method(), binary(), any(), headers(), Keyword.t()) :: HTTPoison.Response.t() | HTTPoison.AsyncResponse.t() | HTTPoison.MaybeRedirect.t()
Issues an HTTP request with the given method to the given url, raising an exception in case of failure.
request!/5
works exactly like request/5
but it returns just the
response in case of a successful request, raising an exception in case the
request fails.
Starts HTTPoison and its dependencies.
Specs
stream_next(HTTPoison.AsyncResponse.t()) :: {:ok, HTTPoison.AsyncResponse.t()} | {:error, HTTPoison.Error.t()}
Requests the next message to be streamed for a given HTTPoison.AsyncResponse
.
See request!/5
for more detailed information.
